TUBB A
TUBB A is a Texas oil lease in Howard County, Railroad Commission district 08, operated by Crownquest Operating, LLC. It has 14 wellbores on file with the Commission. Reported production runs from January 2012 to August 2026, totalling 429,293 barrels. The lease is currently producing. Fitting a decline curve to that history and pricing the remaining production at today's forward curve values the whole lease — a 100% undivided interest — at about $4.5M, with roughly $978K expected over the next twelve months. An individual royalty owner receives their own decimal interest times that figure. Over the last twelve months on file it averaged 1,509 barrels a month, about 108 per wellbore. Its strongest month on the record we hold was June 2016, at 7,761 barrels. In our own backtest, leases producing at this rate are forecast to within about 17% of what they went on to produce, and that measured error is the range shown on the page rather than a confidence of our own devising.
